BAR OR FASTENER FOR DOORS.

SPECIFICATION forming part Of Letters Patent No. 698,326, dated April22,1902.

Application filed December 21, 1901. Serial No. 8d, 77l. (No model.)

To all whom it may concern/.1 Be it known that I, BENJAMIN SOHWAB, acitizen of the United States, residing at Nogales, State of Sonora,Mexico, have invented; certain new and useful Improvements in Bars orFasteners for Doors, of which the following 'be operated from the insideby a knob and from the outside by a key and which maybe locked in such away upon' the inside that the key will not slide the bar or bolt topermit the door to be opened. Ordinary bolts,

' bars, or looks furnish butllittle protection against heavy shocks,blows, or against prying from the outside. My invention serves as asecure barrier against successful attempts to enter'the door, even if akey be used, provided the inmates of the house desire to lock the barfrom sliding. i

My device may be used with either single or double doors of any widthand which swing to the right or left. I I

I attain the objects referred to bymeans of the construction illustratedin the accomp'a nying drawings, which form a part ofthis specification,and in which Figure 1 is a perspective view of a doorfastener embodyingmy invention. Fig. 2 is a perspective view of a lock and certainattachments thereto which I use in connection with my door-fastener.Fig. 3 is a central vertical section through a ball-bearing 'guide 1adapted to be secured to the lock. Fig. 4 is a side view and partialsection of a guide loop and keeper, to be hereinafter referred to.

Like numerals designate like parts wherever ishey occur in the differentviews of. the drawngs.

The numeral 1 designates a lockof ordinary or any suitable constructionprovided with a sliding bolt 1, which may be moved to the right or leftby the knob 2 or by the key 3, inserted within the tube 2, said tubedesigned to be passed through the door and forming a flush keyhole onthe outside of said door. The keeper 3 for the bolt 1' is secured to thedoor-frame or to one of the doors if my device is to be used with doubledoors. A strong 7 metal bar 4 is mounted to slide to the right or leftwiththe bolt 1. A ball-bearing guide comprising the two parts 5 6 issecured to the door immediately above the lock 1, a raceway 6' beingformed between'the parts 5 6 for the ball 7, a plurality of which ballsmay be utilized, if found desirable. At one end of the bar 4 a notch 4is formed, for a purpose which will be hereinafter referred to. The bar4 is supported at one end in a combined keeper and hinge 8 8, the member8 of which is securely fastened to the door-frame. Secured to'the bolt 1is a bracket 9, provided with an integral lug 9, and a loop or guide 10is bifurcated at its lower end to straddle the lug 9, as will be seen inFig; 2. A set-screw 11 passes through the upper end of the loop 10 andis adapted to bear against the upper edge of the bar 4 to secure the barto theloop andv to insure the movement of saidbar when the bolt 1 ismoved in either direction. A loop or guide 12, provided with an integrallug 12, Fig. 4, designed to fit and slide in the keeper 14, has aset-screw 13 passed throu'gh'its upper end and adapted to bear againstthe upper edge ofthe bar 4 to move with said bar when it is desired topermit the bar 4 -to be operated by the key 3. door-frame opposite thehingeS to engage the A keeper 15 issecured to the free end of the bar 4.

The operation of my invention is as follows 2 Whenever it'is desired tobar the door in such a manner that it may be unlocked by the key 3, theset-screw 11 is turned "down to bear with sufficient force against; thebar 4 to in sure the movement of the banwith the loop 10 and the bolt 1.If it is desired to secure the door against the operation of the bar 4by the key 3,the set-screw 13 is-turned down sufficiently to throw theshoulder of the notch 4 up to engage the upper wall of the keeper 8',the bar 4 being fulcrumed upon the'ball7 to rock sufficientlyforthispurpose;

From the foregoingit will beobseryed that my door-fastener furnishes avery secure barrier against intruders, that the devicemay be applied todoors of any width, and that the device is of comparatively simpleconstruction and may be produced at small cost.

It will be understood that a combinationlock may be used instead of thelock and key shown in the drawings;

When the bar 4: has been unlocked, it can be readily removed and setaside until it is necessary to use it again, when it may be instantlyreplaced for operation.

Having thus described myinvention, what I claim is- 1. A barrier fordoors comprising a look, a bar connected to the bolt of said lock to bemoved therewith, and a ball-bearing guide for said bar, substantially asdescribed.

2. A bar for doors consisting of'a look, a bracket attached to the boltof said 1ock,a barrier connected to said bracket to be moved with thebolt, one end of said barrier engaging a hinged keeper, substantially asdescribed.

3. A bar for doors comprising, a look, a bar rier connected to the boltof said lock, to be BENJAMIN SCIIVVAB.
